Application led April 1,

To all whom t may concern:

Be it known that I, HEINRICH Onrcms, citizen of the German Republic,residing at No. 30 Cyriakstrasse, in the city of Erfurt, Germany, haveinvented certain new and useful Improvements in Self -Loading Pistols,for which I have tiled application in Germany February 8, 1918, of whichthe following is a specication.

The present invention relates to self-loading pistols of the kind whichare fitted with a removable breech part secured against removal by meansof a releasable catch and with a cooking lever which when the butt orhandle is gripped is forced inwardly into cocked position and therebycocks the liring pin. The object of the invention is to provide for suchpistols a simple, strong and readily released holding device for thecocking lever, when the latter has been moved into cocked position,which device will automatically snap into the holding position and maybe released therefrom by a simple pressure on a push piece, and which,when in holding position, will simultaneously and automatically engagethe catch for the breech. According to the invention there is providedin the handle of the pistol a push bolt, which is under action of aspring and axially movable, and which, when the cocking lever is incocked position engages with a collar in a recess in the latter. Thisbolt has a nose which, when the bolt is in holding position, c'. e. whenthe pistol in ready for shooting, will engage in a groove in the breechpart.

The accompanying drawing illustrates an embodiment of the pistolaccording to the present invention. Figure l is a longitudinal section;Fig. 2 is a cross-section along the line 2 2 in Fig. l, the catch memberbeing released. Fig. 3 is a fragmental sectional view similar to Fig. l,but showing the catch in looking position; Fig. 4: is a cross-section online lc-4, Fig. 3; Fig. 5 is a perspective View of the upper portion ofthe cooking lever, and Fig. 6 is a perspective view of the catch member.

The breech member a of the pistol is held, when the pistol is ready forshooting, by the nose b engaging in a groove in the breech member, saidgroove permitting a longitudinal movement of the breech member; therebythe breech member is prevented from moving in an upward direction. rIhisnose b, -which heretofore was brought into Specification of LettersPatent.

the cooking lever c is pivoted in known mant' ner, the arm 7@ of whichforms likewise in -known manner the abutment for the percussion pinspring. According to the present invention the cooking lever is providedwith a recess 7L which encircles the bolt c between the head z' and thecollar y' from right to left. The collar j may engage with a recess 7cin the cooking lever, corresponding to its form.

rIhis will be the oase when the lever e isforced inward on the handlebeing gripped. The spring Z will then force the collar j into the recessle, so that the latter encircles the same and it is impossible forthevcocking lever to go back. In this position the pistol is ready forshooting, and a continuous firing is possible without any strain on thehand by the cooking lever. When the collar j thus engages in the recess7c the nose ZJ will at the same time engage the breech part a, so thatit is impossible for the latter to move upward, whether purposely oraccidentally. By exerting pressure on the head z' of the bolt c .thecollar is disengaged from the recess is, whereupon the cooking lever isforced back by the action of the firing pin spring and the pistol issafe, as the tiring pin spring is relieved. At the same time the nose Z)is disengaged from the breech member, so that the latter may, whendesirable, be removed without any difficulty.

Ihat I claim to secure by Letters Patent of the United States is 1. Inan automatic pistol, the combination, with a cooking lever having arecess therein; of a bolt mounted for axial sliding movementtransversely of the handle of the pistol and provided with a collarconforming to the shape of said recess but normally disalined therefrom;and a controlling spring acting to automatically shift said bolt axiallyin a direction to engage said collar in said recess when the cookinglever has been forced inward, whereby said leverwillv be locked againstreturn movement.

2. In an automatic pistol, the combination, with a cooking lever havinga recess therein, of a bolt mounted for axial sliding movementtransversely of the handle of the pistol and providedv with a collarconforming to the shape of said recess but normally disalined therefrom;and a controlling spring acting to automatically shift said bolt axiallyin a direction to engage said collar in said recess when the cookinglever has been forced inward, whereby said lever will be locked againstreturn movement; said bolt having a presser head which projectsexteriorly of the handle to permit the bolt to be pushed inwardlyagainst the action of said spring to disengage said collar from saidrecess.

3. In an automatic pistol, the combination, with the sliding breechmember and the cocking lever, said member being provided with a grooveand saidlever with a recess; of a bolt Vmounted for axial slidingmovement transversely of the handle of the pistol and having a collarconforming to the shape of said recess but normally disalined therefrom,said bolt also having a nose for engagement in said groove; and acontrolling spring acting to automatically shift said bolt axially Y ina direction to simultaneously engage said collar in said recess and saidnose in said groove, when the cooking lever has been forced inward,whereby said lever will be locked against return movement and saidbreech member against upward movement.

4. In an automatic pistol, the combination, with the sliding breechmember and the cooking lever, said member being provided with a groove;of a bolt mounted for axial sliding movement transversely of the handleof the pistol and having a nose engageable in said groove to lock thebreech member against upward movement; and a controlling spring actingto automatically shift said bolt axially in a direction to Veffect theengagement of said nose when the cooking lever has been forced inward.

In testimony whereof I have aliixed my signature.
